Application December 9, 1944, Serial No. 567,501

` 2 Claims. l(Cl. 3054-10) '(Granted under the act of March 3, 1883, as

amended The invention described herein may be manufactured and used by or for the Government for governmental purposes, without the payment to me of any royalty thereon.

This invention relates generally to tracks for track laying vehicles and more particularly to track shoes with grousers forming a part of the tracks.

n All track shoes made according to the teachings of the prior art, and with which I am familiar, have had no practical meansfor attaching a grouser to a track and it has been practically impossible to use grousers with steel tracks.v The chevron and other type `cleats have been formed on steel shoes of solid construction. f Much material was required and when the cleats wore off, the shoe was of little use. End connections have been utilized for attaching grousers to-tracks with rubber shoes, but the connections have been found very poor and they have been very difcult to connect and disconnect from the track. No means have heretofore been provided for attaching a grouser to a shoe of steel, especially where such grouser must bear the weight of our heaviest tank vehicles.

It is, accordingly, an object of my invention to overcome the above and other defects in track shoes with grousers attached and it is more particularly an object of my invention to provide a track shoe with grouser attached which is simple in construction, economical in cost, and efficient in operation.

Another object of my invention is to provide a removable ground plate or grouser for a steel track shoe.

Another object of my invention is to provide novel means for attaching a base plate and a ground plate or a grouser together.

Another object o f my invention is to provide a v connected base plate and a ground plate or grouser which will withstand the pressure of the heaviest vehicle.

Otherobjects of my invention will become evident from the following detail description, taken in conjunction with the accompanying drawing,

in which:

Figure l is a view taken upwardly from the ground showing my novel track shoe in assembled position;

Figure 2 is a side elevational view of the base plate of my novel track shoe;

Figure 3 is a side elevational View of the ground plate or grouser of my novel track shoe;V

Figure 4 is a side elevational View of the screw bolt and lock washer used in fastening 'together spaced apertures April 30, 1928; 370 0. G. 757) the base block and ground plate of my novel track shoe;

Figure 5 is a -vew taken on the line -5-5 of Figure l. f

Referring to the drawing, Figure l shows a base plate I having sprocket engaging apertures 2 and 3, spaced apertures` 4 and 5, and a centrally disposed aperture 6. A guide pin 'I is integral withand extends upwardly from base plate I and has a cross aperture 8 connecting with the centrally disposed aperture 6. Offset bosses 9 extend laterally from the base plate I and have apertures YI il extending therethrough adapted to receive connecting pins not shown. The ground plate or grouser I I has a seating surface I2 and an irregular depending cleat i3 extending downwardly therefrom. Spaced pins I4 integral with the seating surface I2 engage the apertures 4 and 5 in the Pins I 4 may be secured by pressing, shrinking or otherwise securing the ends of the pins I4 in the apertures 30 in the surface I2. The pins I4 prevent relative lengthwise and sidewise movement between the base block I and the ground block II. Seating surface I2 has a centrally disposed aperture I5 alined with the aperture E in the base plate I and into which extends a screw bolt I6 which engages a trapezoidal shaped nut I1 to fasten the ground plate II and the base plate I together. A lock washer I8 prevents relative rotation of the bolt I6 and nut I'I. Recesses 3I are provided to reduce the weight of base plate I to a minimum.

base plate I.

It will be evident that any form of ground plate Y may be used as long as the seating surface I2, spaced pins I4, and a centrally disposed aperture I5 are provided. The aperture 8 in the guide pin 1 thereby preventing rotation thereof while the bolt cned. This makes for simplicity in connecting the ground plate I I and the base plate I together..`

Various changes maybe made in the specic embodiment of my invention without departing from the spirit thereof, orv from the scope of the appended claims.

What I claim is:

l. A track shoecomprising a base plate having and a centrally disposed aperture, a guiding pin extending from said base plate having a transverse aperture connected to said centrally disposed aperture in said base plate, a ground plate having spaced studs for disposal in the spaced apertures'in said base plate and a centrally disposed aperture, a threaded nut for disposal in the transverse aperture in said guiding pin and a threadedbolt extending through the nut I'I ts snugly in theV l I6 is being tightcentrally disposed apertures in said ground plate and said base plate and threadably engaged with said threaded nut.

2. A track shoe comprising a base plate having spaced apertures and a centrally disposed aperture, a guiding member on said base plate having an apertured portion connecting with said centrally disposed aperture in said base plate, and a ground plate having spaced studs for engagement with the spaced apertures in said base plate and a centrally disposed aperture, a bolt extending through said centrally disposed apertures, and a. fastening member disposed in the apertured portion of said guiding member for engagement with said bolt.
